示例1: __construct
function __construct($object, $parameters = null)
{
if ($object instanceof Product) {
$this->item = ShoppingCart::get_item_by_id($object->ID, null, $parameters);
//provide a 0-quantity facade item if there is no such item in cart
if (!$this->item) {
$this->item = new Product_OrderItem($object, 0);
}
//TODO: perhaps we should just store the product itself, and do away with the facade, as it might be unnecessary complication
} elseif ($object instanceof OrderItem) {
$this->item = $object;
}
if (!$this->item) {
user_error("EcomQuantityField: no item or product passed to constructor.");
}
$this->parameters = $parameters;
//TODO: include javascript for easy update
}示例2: Item
function Item()
{
if ($item = ShoppingCart::get_item_by_id($this->ProductID, $this->ID)) {
return $item;
}
return new ProductVariation_OrderItem($this, 0);
//return dummy item so that we can still make use of Item
}示例3: Item
/**

* Note : This function is usable in the Product context because a
* Product_OrderItem only has a Product object in attribute
*/
function Item()
{
$filter = null;
$this->extend('updateItemFilter', $filter);
$item = ShoppingCart::get_item_by_id($this->ID, null, $filter);
//TODO: needs filter
if (!$item) {
$item = new Product_OrderItem($this, 0);
}
//return dummy item so that we can still make use of Item
$this->extend('updateDummyItem', $item);
return $item;
